Open Api Inheritance

I am defining and api in Open Api.

And this work ok. But now i am running into a problem.

ChildEvent:
  type: object
  discriminator:
    propertyName: eventTypeCode
    mapping:
      product: 'ChildEventProduct'
      sleep: 'ChildEventSleep'

This will generate the correct class But can i make it abstract and it will not generate the 2 sub classes.

ChildEventsForPeriodResult:
  type: object
  properties:
    events:
      type: array
      items:
        $ref: 'Events.yaml#/ChildEvent'

DirtyHolder:
  type: object
  properties:
    sleep:
      $ref: 'Events.yaml#/ChildEventSleep'
    product:
      $ref: 'Events.yaml#/ChildEventProduct'
ChildEvent:
  type: object
#  oneOf:
#    - $ref: 'Events.yaml#/ChildEventSleep'
#    - $ref: 'Events.yaml#/ChildEventProduct'
  discriminator:
    propertyName: eventTypeCode
    mapping:
      product: 'ChildEventProduct'
      sleep: 'ChildEventSleep'

  properties:
    id:
      type: integer
      format: int64
    startTime:
      $ref: 'General.yaml#/DateNoTimeZone'
    endTime:
      $ref: 'General.yaml#/DateNoTimeZone'
    roomId:
      type: integer
      format: int64
    comment:
      type: string
    repeatingEventId:
      type: integer
      format: int64
    childId:
      type: integer
      format: int64
    dayCareReportId:
      type: integer
      format: int64
    privateEvent:
      type: boolean
      default: false
    importantEvent:
      type: boolean
      default: false
    markForExport:
      type: boolean
      default: false
    groupEventId:
      type: integer
      format: int64
    eventCode:
      type: integer
      format: int32
    partyId:
      type: integer
      format: int64
ChildEventProduct:
  allOf:
    - $ref: 'Events.yaml#/ChildEvent'
    - type: object
      properties:
        productId:
          type: integer
          format: int64
ChildEventSleep:
  allOf:
    - $ref: 'Events.yaml#/ChildEvent'
    - type: object
      properties: {}

This is the complete yaml file. What is wrong with this. Dirst i thougt it was the generator but it alos fails when generating the andoid client

Can this be done?
